7Required properties:
8  - compatible: must be "maxim,max30102" or "maxim,max30105"
9  - reg: the I2C address of the sensor
10  - interrupts: the sole interrupt generated by the device
11
12  Refer to interrupt-controller/interrupts.txt for generic
13  interrupt client node bindings.
14
15Optional properties:
16  - maxim,red-led-current-microamp: configuration for red LED current
17  - maxim,ir-led-current-microamp: configuration for IR LED current
18  - maxim,green-led-current-microamp: configuration for green LED current
19    (max30105 only)

21    Note that each step is approximately 200 microamps, ranging from 0 uA to
22    50800 uA.
